CORN-CUTTER.

lb-all whom it may concern:

Be it known that I, HUGO BGHNER, a subject of the German Emperor,residing in Berlin, Germany, have invented certain new and usefulImprovements in Corn-Cutters, whereof the following is aspeciiicatiomrefcrence being had to the accompanying drawings.

My invention relates'to a cutter or plane tor shaving corns.

It consists essentially of a clamping plate and a base plate betweenwhich a thin cutting blade is rigidly clamped with proper expo-:ure ofthe cutting edge for operative purposes. may operate as a plane, it iscaused to project beyond the corresponding edge ot the clamping plate,and the further projecting odg'.I oi the base plate is inclined. andslotted so that by coperat'ion with the rounded outer surface of theclamping plate, a planing surface is provided, with an .escape slot inlproper correspondence with each cutting et ge.

illustrated and will particularly describe, the blade has two operativecutting edges and the clamping parts are correspondingly formed withbilateral symmetry. In addition to these parts, I provide a centralhandle which Serves both to manipulate the instrument, and also incooperation with a stem to clamp the blade between the two plates. Bythe arrangement of parts thus described and illustrated, the instrumentis laterally symmetrical with two planing edges available for immediateuse at all times.

In' the accompanying drawings, Figure I, is a front elevation of 'a corncutter embodying my invention. Fig. II, is a side elevation ot"V thesame.v Fig. III, isa section through the clamping plate with Stemattached. Fig. IV, is a plan view of the base plate. Fig. V, is asection along the line A, A, of Fig. IV. Figs. VI, VII, VIII, and IX,are perspective views showing respectively the clamping plate, the.blade, -the base plate and the handle, in position for assemblage. Fig.X, is a section of the base plate as employed in a modified form wherethe stem forms part of the handle insteadof being attached to theclamping blade. Fig. XI, is an elevation of part of the handle to beused in combination with the modification of Fig. X.

In order that the cutting edge In the'preferred construction which Ihave Specification of Letters Patent. Patnted Jan, 31, 1911,

Application filed October 1 6, 1909.

Serial No. 523,008.

rIlhe blade 1, of my cutter is preferably provided with at least twocutting edges 2, 2. The blade is somewhat wider than the clamping partsand the other two projecting edges 3, 3, as shown in Fig. II, arepreferably of rounded contour for the more ready manipulation andadjustment of the blade when setting it. within the holder. The blade isprovided with a central aprture et, through which a clamping lstempasses, and other apertures 5, 5, co-acting with centering pins, andserving to accurately tix the position of the blade im the holder.

My instrument further comprises two opposed plates, a clamping plate 6,and a base plate 7. The shape of the clamping plate best appears fromthe drawings, Figs. III, and VI. It is there shown as combined with acentral stem 8, which passes through the central aperture 4, oftheblade, and also withtwo centering pins 9, 9, co-acting with theapertures 5, 5, of the blade. When the blade is adjusted in relation tothis clamping plate, the cutting edges of the blade are parallel to butproject slightly beyond the corresponding edges of the clamping plate.rIhe upper surface of the clamping plate between thesetwo edges presentsa` curved contour, as illustrated. Y

The base plate, as shown in Figs. IV, V,

and VIII, is larger than the clamping plate.

It likewise has a central aperture 10, which receives the stem and otherapertures 11, 11, which receive the centering pins. The base plate is"urtherpierced with two escape slots 12, 12, in parallel relation andnear opposite edges of the plate, in such position that the slotsproperly correspond to the edges of, the blade, when the latter isseated on the outer face of the base plate in its proper osition. Thelength of the cutting edge ofp the blade being greater than the lengthof the slot, the ends or col'ners of the blade are protected fromexposure. Coincident with and beyond the escape slots, the base plate isdownwardly inclined to form the planing surfaces 13, 13, the inclinationappearing clearly from Fig. V. These ineline planing surfaces, are sorelated to the `upper curved surface ofthe clamping blade, as to form avslightly rounded but, if the portions adjacent to the edge of the bladebe considered, a practically flat continuous planingsurface with thecutting edges of the blade interposed in proper coincidence with theescape slots, and with both inclined planing surfaces in similarsymmetrical relation to the central handle.

The stem 8, in the construction illustrated within a threaded socketl,in the handle,

as shown in Fig. IX. When the parts are thus assembled in the orderillustrated in Figs. VI, to IX, the adjustment and screwing up of thehandle, aEords the requisite pressure to clamp the. blade in placebetween the clamping' plate, and the base plate. When thus arranged, thetool is a new article of manufacture Witl a central handle, and planing`surfaces symmetrically arranged in proper inclination to said handle,andV with escape slots, and cutting edges interposed wit-hin the planingsurfaces so that both edges of the blade may with equal facility be usedfor the purpose of cutting or paring down corns.

In the modified form of construction shown in Figs. X, and XI, the stem20, instead of forming part of the clamping blade, is integral with andprojects from the head of the handle, so that afteradjusting the baseplate and, the blade upon the stem, the protruding threaded portion ofthe stem may be screwed into the corresponding central aperture of theclamping plate, which operation1 similarly clamps the essential parts ofthe tool with the blade in position.

Having thus described my invention, I claim:'- A

l. A corn cutter comprising a handle, a slotted base plate, abladeseated on the outer .fa-ce of said baseplate, with its cutting edgeoverlying said slot and located between its side edges and extendingbeyond the ends of said slot, a clampin plate resting upon the outerface of said bIade adjacent its cutting edge, and means for clampingsaid plates together, with the blade between them.

2. A corn cutter comprising a handle, a

' slotted base plate, a blade, and a clamping plate; a screw stem bywhich these four parts are clamped together in the order named, with`the cutting edge of the blade overlying the slot of the base plate; andwith said base plate projecting beyond said cutting edge; the outersurface ofthe projecting portion of the base plate and the outer surfaceof said clamping plate adjacent to said edge forming a practically ilatand continuous planing surface with 'the edge slightly exposed.

3. The combination of a double-edged blade; a' double-edged base plateprovided near two opposite edges with parallel escape slots at suchdistance that when the blade is seated on the base `plate its edges .arecoincident with and. overlie the escape slots; a clamping plate; acentral handle;

centering means for fixing the relation of the parts, and clamping meansoperable by the handle, whereby the blade is clamped between theclamping plate and the base plate.

4. The combination of a double-edged blade; a double-edged base plateprovided along two opposite sides with inclined planing surfaces, escapeslots formed in these inclined planing surfaces parallel toeach otherand at such dista-nce that when theblade is seatedon the base plate itsedges are coincident with and overlie `the escape slots; a clampingplate with straight edges corresponding to the cutting edges of theblade,

and with a curved Yupper surface coperating with the inclined planingsurfaces of the base plate to form a continuous planing surface; acentral handle;and a screw threaded stem whereby by rotation of thehandle, the blade is clamped between the clamping plate and the baseplate.

I n testimony whereof, I allix my signature in the presence of twowitnesses.
